I read through all of the discussion that I could find. There was quite
a lot, so perhaps I have forgotten pieces of it.

But that one section in the docs does look out of date and/or confusing
to me.

I remember there was discussion about a way to ensure that checksums are
set cluster-wide with some kind of special command (perhaps related to
VACUUM) and a magic file to let recovery know whether checksums are set
everywhere or not. That doesn't necessarily conflict with the GUC though
(the GUC could be a way to write checksums lazily, while this new
command could be a way to write checksums eagerly).

If some consensus was reached on the exact user interface, can you
please send me a link?

Regards,
	Jeff Davis
